Hi, 
You can at least define the color scheme in a language-wise way.
Go to Settings / Highlighter settings... and then modify the color scheme for
each desired language.
If you mean extension-wise for the same language (e.g. different color scheme
for .h, .c, .cpp... for C/C++ highlighter), then this is not possible.

I personaly prefer the same color scheme for any language...
Anyway, you can save your favorite color schemes and recall it later by saving
the settings in the highlighter settings window.
